[Linux-cluster] ccsd[846]: Error while processing get: No data available



Hi,

We have been running a gfs cluster for a few months with no issues, however we are experiencing a problem with one of the nodes (web4). The summary of the behavior is that after running our startup scripts (broken into individual commands below) one of the nodes (web4) can not mount shared partitions (from a SAN). Looking at the logs it looks like "cman_tool join" throws some errors when invoked "ccsd[846]: Error while processing get: No data available". The configuration on this machine is identical to the other 4 machines which are functioning fine in the cluster. Any help is appreciated.

Below is the cluster.xml file we are currently using followed by the commands performed to get the cluster up and running.
